JoyIn releases Aether embodied intelligence model and questions OpenAI distillation

On September 10, 2026, Suzhou-based JoyIn released the Aether embodied intelligence model, aimed at humanoid robot body control and real-world task execution. JoyIn says the model was trained on about 200 hours of human video and zero real-machine data, has roughly 4 billion parameters, exceeds 90% success rate on first attempts at some tasks, can run on bodies from Unitree Robotics, AgiBot and others, and that it plans to partially open up the model's capabilities.
